Locksmith Security Systems 4 — Questions and Answers
Question 1: What is the main function of a central station in a monitored alarm system?
- To program the alarm panel remotely
- To receive alarm signals and dispatch emergency responders (Correct answer)
- To recharge the panel's backup battery via internet
- To provide real-time video surveillance to homeowners
Correct answer: To receive alarm signals and dispatch emergency responders
Central monitoring stations receive alarm signals 24/7 and coordinate the appropriate emergency response on behalf of the subscriber.
Question 2: Which standard governs the installation of burglar alarm systems in the United States?
- NFPA 72
- UL 681
- ANSI/SIA CP-01 (Correct answer)
- IEC 60839
Correct answer: ANSI/SIA CP-01
ANSI/SIA CP-01 is the Control Panel Standard that defines false alarm reduction features for alarm control panels in the US.
Question 3: What does a 'swinger shutdown' feature do on an alarm panel?
- Locks the keypad after repeated wrong codes
- Stops reporting repeated activations of the same zone after a set number of trips (Correct answer)
- Disables the siren after a timed period to comply with noise ordinances
- Prevents the system from arming if a zone is faulted
Correct answer: Stops reporting repeated activations of the same zone after a set number of trips
Swinger shutdown silences repeated reports from a repeatedly-triggered zone to prevent alarm fatigue and false dispatches.
Question 4: In access control terminology, what does 'tailgating' (piggybacking) refer to?
- Cloning a proximity card to gain unauthorized access
- An unauthorized person following an authorized person through a secured door (Correct answer)
- Brute-force entering a PIN code at a keypad
- Installing a skimmer on a card reader
Correct answer: An unauthorized person following an authorized person through a secured door
Tailgating occurs when an unauthorized individual slips through a controlled door by closely following a legitimate cardholder.
Question 5: A mantrап (airlock) entry system is designed to prevent which security threat?
- Electronic eavesdropping
- Tailgating through secured access points (Correct answer)
- Card reader skimming
- Brute-force attacks on PIN pads
Correct answer: Tailgating through secured access points
A mantrap requires each person to be individually authenticated in an enclosed vestibule before a second door can open, preventing tailgating.
Question 6: What type of sensor is most appropriate for detecting an intruder who has already entered a building and is moving inside?
- Door/window contact
- Glass break detector
- Passive infrared motion detector (Correct answer)
- Vibration sensor
Correct answer: Passive infrared motion detector
Interior PIR motion detectors cover open areas inside the premises and will detect movement after perimeter sensors have been bypassed.
Question 7: Which term describes the practice of programming a delay period before an alarm is transmitted after a door is opened?
- Exit delay
- Entry delay (Correct answer)
- Abort delay
- Response delay
Correct answer: Entry delay
An entry delay gives an authorized user time to reach the keypad and disarm the system after entering through a designated entry point.
